If you are between 11.0.0 and 11.2.0, you must follow this guide to downgrade your NFIRM using one of the methods at the bottom of this page to directly dump and restore your NAND. {: .notice--info}

This will work on New 3DS, Old 3DS, and 2DS (although the DSiWare methods have some restrictions). {: .notice--success}
